A user reports that during high-load tasks, such as rendering video or running computational simulations, their workstation powers off without warning. You have determined through investigation and elimination that the issue is likely related to thermal management. What should your next step be to mitigate this issue?
Install a new thermal management system for the central processing unit.
Install additional case fans to improve overall airflow within the chassis.
Update the operating system to the latest version to ensure all software is up-to-date.
Increase the size of the hard disk to provide more storage for user files.
